IMPROVEMENT IN OIL-BURNING APPARATUS.

TO ALL WHOM IT MAY CONOERN Be it known that I, A. J. WHITE, of BallstonSpa, county o-tSaratoga, State of New York, have invented an Improvementin Lamps or Oil-Burning Apparatus; and I do hereby declare that thefollowing, taken in connection with the drawings which accompany andform a part of thisspecication, is a description of my inventionsuilicient to enable thoseskilled in the art to practise it.

The invention relates to the illumination of buildings with hydrocarbonliquids or oils.

The mode of illuminating a building with this invention is as follows:'In the lower room ot' the building,' or, what is better, in anout-house, situated as low as'the 'lowest room to be lighted, I' place areservoir,with force-pump. To this force-pump are attached iron pipes,which are conducted up to the top of the building to be lighted, andthen through the upper room, then down' and through the next room below,and then to the next, and so on, in one continuous line of pipe,`throughall the rooms to be lighted, and back to the reservoir. EPerpendicularorV pendent pipes are attached to this continuous line of pipe at suchpoints as lights are desired. To eachof these pendent pipes is attacheda. wick-tube or burner, connected with a stop-cock and small reservoir,as shown in the drawing. Y u,

a denotes the wicktube or burner', with a pipe entering it a shortdistance from its top, as shown by b. This pipe Z1 is bent nearly atright angles about four inches from the burner, and to the other end isattached a stop-cock, e. This stop-cock isconstrueted as follows: Itscylinder has two openings, top and bottom,.the lower one `for theattachment of the pipe 6, and the upper one for the attachment of oneot' the pendent pipes before mentioned. The stem or plug of this cockishollow, with an opening in one side and an opening in one end. Theopening in the side of the stem is so Varranged as to correspond withthe openings n the cylinder of the cock. To the opening in the end ofthe stem is attacheda small reservoir, c, which is made to serve as ahandle ot' the cock. When the pendent pipes are iilled with oil, ashereinafter shown, this burnen, cock, and reservoir will be used asfollows: The handleor reservoir c will be turneddown-as ,shown in thedrawing by the full lines d. The opening in the side of the stem oi' thecock will now be opposite the openingr in' cylinder of the cock, on itsupper side, which will allow the oil in the pendent pipe'to iiow'throughthe hollow stem in'to the reservoir c, the air contained-in thereservoir passing up into the pendent pipe, taking the place of the oil.The handle ofthe cock or re'servoir c is now turned up, as shown inthe'drawing by the dotted lines. The openingin the stem of the cockisnow opposite to the lower opening oi' the, cylinder of the cock, which.will allow. the oil to ilow down from the reservoir c through the pipeb, into the ,burner a, air passing up and taking its place until theopening in the side'ot` the Vwich-tnbe is closed by the presence ot'oil, when it will remain stationary. When the lamp is lighted the oil isconsumed till it uncoversthe opening in the wick-burner, when air willagain pass up into the reservoir e, and oil iiow down again into thewick-tube, this process being repeated until all the oil in thereservoir c is consumed, when the reservoir is turned down again andrefilled as before.

When burners are attached to all of the.pendent pipes they areiilledwith oil in the following manner-z The large reservoir is illerlwith oil; then, by working the pump, the oil will be forced up throughthe continuous pipe, and the air contained in the pipe will be forcedbefore the oil until it escapes through the cnd of the return-pipe, andwhen thepipe is filled with oil, air will cease to escape throngh theend of the return-pipe, and oil will flow in its stead into thereservoir. While the oil is passing through this continuous pipe thependent pipes and the small reservoirs attached to them will be lilled.The small reservoirs will be turned down while the pipes are being lled.After the pendent pipes are filled, a cock attached to the pump for'thatV purpose is opened, and all the remaining oil in the continuouspipe is allowed to iiow back into the reservoir. This process isrepeated daily when the lamps v'are in use. It is intended that thesmall reserv0irs,ic, shall hold suiiicient oil to last oneV evening.

The essence of this invention consists in the construction of awick-burner, pipe, and movable reservoir, combined with a hollow-stemcock', so'as to supply the wick-tube with oil as fast as it shall beconsumed, with- Ollt .any danger flOm 0VtllOWage,l and applying thesewich-tubes to lines of pipe, from which the movable reservoirs aro to bcsupplied with oil.

I claim the combination of a wick-tube, a; and pipeZz, with a movablereservoir, e, attached to a hollow-` stem cock, the whole arranged so asto operate substantially as set forth.
